This research is in the form of a case study, using direct data collection methods (surveys) and laboratory tests. Analysis of the data on the level of erosion hazard (TBE) using the USLE calculation approach. The research variables were rainfall erodibility, soil erodibility, slope length and slope, crop management, and land management. The results showed that in the District of Ngargoyo: 1) areas with a very heavy level of erosion hazard covering an area of 500.66 hectares spread over Kemuning Village, Ngargoyoso Village and Nglegok Village; 2) Agricultural activities greatly affect the level of erosion hazard in the study area
